Curious about Actual NetApp NCIE (NS0-516) Exam Questions?

Correct : A, B, C

Target username and password: These credentials are used by the initiator to authenticate to the target.

Initiator username and password: These credentials are used by the target to authenticate the initiator.

CHAP: Challenge-Handshake Authentication Protocol is used to set up the authentication mechanism.

Modifications in the /etc/iscsi/iscsid.conf file include setting the appropriate values for these parameters.

Reference: NetApp iSCSI Configuration Guide for Linux, which details the configuration of CHAP and other authentication methods.

Correct : B, D

Understand Pre-Upgrade Health Check:

Purpose: The pre-upgrade health check is designed to ensure the system is in a stable state before proceeding with firmware or software upgrades. This helps to avoid disruptions and data loss.

Volumes on Non-Preferred Path (B):

Issue: If volumes are reported on a non-preferred path, it indicates that there might be a pathing issue or an imbalance in the I/O load.

Impact: Non-preferred paths can lead to performance degradation and increased latency, which might cause issues during the upgrade process.

Resolution: Ensure that all volumes are accessible through their preferred paths before initiating the upgrade.

I/O Being Processed (D):

Issue: Active I/O during the upgrade process can lead to incomplete or failed upgrades.

Impact: Processing I/O during an upgrade can result in data corruption or loss, and may also cause the upgrade to fail.

Resolution: Suspend or stop all I/O operations on the system before starting the upgrade.

Correct : A

Access the Interoperability Matrix Tool (IMT):

Step: Open the NetApp Interoperability Matrix Tool.

Reason: The IMT provides a comprehensive list of supported configurations, including specific versions of drivers and firmware for HBAs.

Navigate to HBA Compatibility:

Step: Search for QLogic HBA compatibility with NetApp E-Series systems.

Reason: To find the exact versions of drivers and firmware that are validated and supported.

Verify the Information:

Step: Cross-reference the information provided by the IMT with the installed hardware.

Reason: Ensuring compatibility to avoid issues related to unsupported configurations.

Correct : A

Identify the Orphaned Volume:

Step: Use SANtricity System Manager to identify the orphaned volume.

Reason: To determine which volume has lost its mirror relationship.

Remove the Mirroring Relationship:

Step: Access the mirroring settings for the orphaned volume and remove the existing relationship.

Reason: The current relationship is invalid and needs to be removed to reset the configuration.

Re-create the Mirroring Relationship:

Step: Establish a new mirroring relationship for the previously orphaned volume.

Reason: To restore the asynchronous mirroring setup with a valid configuration.

Correct : D

Understand ALUA Path Configuration:

Step: Review the exhibit to determine the paths between the host and the EF280.

Reason: ALUA (Asymmetric Logical Unit Access) provides multiple paths for redundancy and load balancing.

Count the Paths:

Observation: Each controller has two ports connected to two separate FC switches, and the host is connected to each switch, providing two paths per controller.

Calculation: 2 controllers x 2 paths per controller = 4 total ALUA paths.
